372 POLYPORACEyE Porothelium 



Closely allied to Fistulina, with which it agrees in the fimbriate 

 mouths of the free tubercles. or tubes. The tubes frequently distil 

 drops of fluid in damp positions. The appearance commonly 

 somewhat resembles effused groups of minute ALcidia. 



Species 1682 — 1686 



Massee places this genus in Hydnacece. 



Fries has made Solenia follow Porothelium ^ but in Solemn each 

 cup or cylinder is a complete plant, not a mere tube. To find a 

 place in the PolyporacecB each cup should be furnished with tubes. 

 The true place for Solenia is after Cyphella in the Thelephoracece. 



1682. P. flmbriatum Fr. (from the fimbriate margin of the subiculum) 



a c. 

 Sub. separable. Pa. hemispherical, immersed, small, biscuit- 

 colour ; marg. broad, barren, fimbriate, white. 



Birch, beech. 3§ in. General appearance much like the pore surface of a 

 minutely pored resupinate Polyporus. Pa. sometimes distant. Often with 

 extensive barren places on subiculum. 



1683. P. Friesii Mont, (after Elias Fries) a b e. 



Sub. less fimbriate than 1682. Pa. hemispherical, immersed, 

 somewhat larger than in 1682, varying from minute to larger, 

 ivory or pale brown. 



Pine, juniper. Sept. -Feb. 3 in. 



1684. P. Stevensonii B. & Br. (after the Rev. Dr. John Stevenson) a. 

 Sub. somewhat thick, gelatinous. Pa. elongate, whitish or pale 



yellowish, each bearing a diaphanous, yellow globule ; marg. 

 rather coarsely hispid, then more or less denuded. 



Pine, squared pine. 3f in. The mycelium imparts a sweet scent to 

 the wood. 



1685. P. Keithii B. & Br. (after the Rev. Dr. James Keith). 



Sub. adnate, gelatinous in centre. Pa. short, collapsing, pallid ; 

 marg. very thin, at first somewhat gelatinous. 



Dead fir. April. 



1686. P. eonfusum B. & Br. (from its having been confounded with 



other members of the genus). 

 Sub. adnate, at first floccoso-pulverulent. Pa. very small, pallid ;
